I am using an OpusA3 with version 3.5 SP17 Patch 3 as part of a project. I had no real problem before I encountered a problem that blocked me.
The detection of the OpusA3 from Codesys is done correctly. The gateway is well configured and if I ping the gateway or the OpusA3 I receive the response correctly.
The problem is that when I try to connect, the Opus screen freezes and a few moments later Codesys displays an error message ("connection to device closed").
I tried to change PC, to update the runtime, to change OpusA3 but the problem remains the same. I'm a little lost knowing that before it worked without problem.
I went back to a previous version of the project (where it worked correctly) but the message still appears.
Do you have any clues to solve the problem?
Sincerely,

is there a way to check the plclog on Opus A3 by using cmd line under Linux? This log is what you need to check for the disconnection problem
Hello,
Exulting the command /opt/CoDeSysControl/Files/run restart debug I get this response from the linux terminal:(ScreenShot1 to ScreenShot7)
When I try to reconnect via codesys this line appears at the linux terminal level:(ScreenShot8)
A few seconds later, the error window appears on Codesys.(ScreenShot9)
I see that following the command /opt/CoDeSysControl/Files/run restart debug there are errors, are they the problem?
Sincerely,
i found this error in /opt/CoDeSysControl/Files
